Question

Write the domain and range as inequalities

Answer 1

Answer:

Domain: -∞<x<∞

range: -2≤y<∞

Step-by-step explanation:

domain is basically all the x values of the set. The parabola is facing up, meaning that it extends forever upward and out. This would mean the x values of the graph reach from neg to positive infinity

range is basically all the y values of the graph. The lowest y value, as shown by the vertex is -2. As said earlier, the parabola is facing upward, extending forever upward meaning that the highest y value is positive infinity

for infinity, always use these < or >

for numbers that are included in the graph such as -2 in this case, use ≤ or≥
